A. B. NIMBS, OF BUFFALO, NEW YORK.

IMPROVEMENT IN COAL-ELEVATOR BUCK-ETS.

Specification forming part of Letters Patent No. 411.108, dated September 6, lStil.

To @ZZ whom it may concern:

Be it known that I, ARHEUNA B. NrMBs, of the city of Buffalo, county of Erie, and State of New York, have invented anew and Improved Coal-Elevator Bucket; and I do hereby de clare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a pait of this specification, in which- Figure I is a top plan Figli, a transverse section and Fig. III, a front elevation.

Letters of like name and kind refer to like parts in each ofthe figures.

The nature ot' this invention consists, first, iu `protecting and strengthening a sheet-metal elevator-bucket ot' coinnion form by means ot' wrought-iron bars or ribs placed vertically upon the outside ot' the bucket equidistant from each other, and welded or otherwise connected to a horizontal bar at the back of the bucket, by which bar the bucket is hung or connected to the carrying belt or chain 5 second, in prolonging the strengthening bars so that they will project upward above the dipping edge of the bucket, and form prongs or fingers which aid and greatly facilitate the iilling ofthe buckets.

A represents the sheet-metal bucket of coinnion form and to which the strengtheningbars are connected.

B B represent the strengthening and protecting bars or ribs, welded or otherwise fast.- ened at equal distances (or nearly so) from each other to the back bar, C,- and to the main body of the bucket. These bars are bent to the form ot' a vertical section of the bucket,

which is fastened to them by riveting or otherwise. They give great stiffness and strength to the bucket, and protect it from bruising' when dippinginto the coal. They also project upward beyond the dipping-edge o'f the bucket, formi-ng prongs or iingers, as shown at b. These prongs not only protect the edge of the bucket from injury, but cause it to enter the coal easily and till itseltl without straining. Without them it would be impossible to till the bucket when thelumps ot' coal were ot' any considerable size, and the dippingedge would soon become so battered and cut as to render the bucket worthless; but the prongs, striking easily into the interstices between tlie lumps, gather them into the bucket without shock or strain.

O representsawrought iron bar placed horizontally across the back edge ot' the bucket to strengthen the sa1ne,aud to which the rear ends of the bars I5 are connected, as before described.

What I claim as my invention,and desire to secure by Letters Patent, isf 1. A coal-elevating bucket having vertical strengthening-bars B and ahorizontal back bar, C, substantially as described.

2. Prolomging` the strengthening-bars B so that they will project upward above the main body ot the bucket, as shown at b', substantially as set forth.
